There is, but I've said this to nearly ever TCL and PHP developer on
earth: I do not understand XML parsing at all, DOM, SAX, xQuery,
X[whatever else], none of it makes sense to me and I cannot understand
the books, tutorials and online guides (not to mention the tips from
far smarter people than I) that has barraged me; all of it makes
absolutely no sense to me.
At this point the only way I can parse XML is using PHP, because that's
literally the ONLY way I can do it, period!
But if you want to see a sample of the XML I'm working with, here it
is:
